Description Adam Michalunio 2017-04-09 18:34:06 UTC
The movement of the pointer is choppy, the tap-click doesn't work at all, the two-fingers scroll doesn't work as well. The touchpad is actually not functional.

I'll need an evemu-record recording of the touchpad to debug this, thanks. See this link for details:

config files and evemu-record

I attached required files
Comment 3 Peter Hutterer 2017-04-26 04:41:23 UTC
ok, first, the touchpad edges are out. please run the touchpad-edge-detector tool and follow its instructions.

This looks much like a duplicate of bug 100463 but there seems to be some extra bug. I'll need a recording of just a two-finger scroll motion please, thanks. Attached as separate file, no tarballs please.
Comment 4 Adam Michalunio 2017-04-26 06:51:28 UTC
I attached the new files from touchpad-edge-detector & evemu-record-two-fingers. Two fingers scroll unfortunately doesn't work.

Comment 7 Peter Hutterer 2017-04-27 03:41:28 UTC
https://github.com/systemd/systemd/pull/5825 for the hwdb fix to adjust the sizes to the correct range.

As for the two-finger scrolling issue, it is bug 100463, after adjusting the ranges locally it seems to work fine. Expect a patch for that to go upstream soon.

touch-pressure statistics

I'm afraid also about a touch pressure. I attached the touch-pressure statistics. Please check what values will be correct.

10:8 should be correct, that's what paul already has, I'm just waiting for a v2 from him.
